I don’t know much about Roblox other than it’s some multiplayer game platform.
Is it down totally with nothing working, or just extremely overloaded but with some requests still getting through?
If it’s totally down still after 24hr it must be pretty serious. I’ve seen my fair share of production fires but usually you can bring some of the service back up quickly and then fight with the thundering herds and load and eventually stabilise the service.
I hope they put out a public post-mortem afterwards.
